TextBox - OnChange Event to validate input

[sgibbs]

I have a form which requires a date to be input. Here is the control:

<input type=&quot;text&quot; name=&quot;StopDate&quot; size=&quot;10&quot; maxlength=&quot;10&quot; onchange=&quot;ValidDate;&quot;>

here is the sub which is supposed to be called:

<% sub ValidDate()

if isdate(request.form(&quot;StopDate&quot) = false then
ErrorText = &quot;Invalid Date Entered&quot;
msgbox errorText
else
msgbox &quot;Success&quot;
end if

end sub
%>

Nothing is happening when I enter data in the control (either success or failure). I can't find the syntax to use the onchange event. Also tried the onblur event with no success. Any suggestions?

Thanks much in advance!

make sure that if you want to use client side validation you make the sub a client side script, remove the <%%> and put it in <Script language=&quot;javascript&quot;> jared@aauser.com
